What students say

★★★★★

I’ve studied with many teachers over the years, and I can confidently say that Chase Bossart stands out as one of the best. His depth of knowledge, clarity of instruction, and ability to truly embody the teachings set his training apart. This program was more than just learning yoga, it was a transformative journey that deepened my understanding of both practice and self. I’m incredibly grateful to have trained under someone so rooted in wisdom, humility, and integrity.

★★★★★

Yoga Well's practitioner and teacher training programs are the most profound Yoga experiences and studies I have found. During my 300 hour training with Mr. Chase Bossart in 2021, I changed all of my personal practice and teaching exclusively to the Viniyoga tradition, began a massive transformation of my life to align with the incredibly clear and supportive principles of Yoga, and committed to Yoga Well's 1000+ hour Yoga Therapist training with full payment up front --- all because the wisdom of humanity and the divine is so easily and diligently accessible in this community. In less than a year during this 300 hour training, I finally got the message of Yoga and will be a lifelong student of Viniyoga. I cannot commend or thank Mr. Chase Bossart, Elizebeth Cunningham Bossart, Amanda Green, Yoga Well's broader staff, and the brilliant community organized here enough. I recommend Yoga Well's Deepen Your Yoga program for any and all teachers and practitioners. It is foremost a container for practitioner's to delve into an experiential learning of Yoga, and second a 300 hour program for teachers ready for highly diligent practices. The same goes for their Yoga Therapist training I am 1/3 of the way through at the time of submitting this review :)
